Data Published in Plastic and Reconstructive Surgery Show Cohera Medical's Surgical Adhesive, TissuGlu(R), Prevents Seroma Formation in Animal Abdominopl...( PITTSBURGH June 19 /- Cohera Medi...),Health

PITTSBURGH, June 19 /PRNewswire/ -- Cohera Medical Inc. today announced that data published in the July issue of Plastic and Reconstructive Surgery show the company's surgical adhesive, TissuGlu, was effective in preventing the formation of seroma in an animal abdominoplasty model.

Summarized in a paper titled "Lysine-Derived Urethane Surgical Adhesive Prevents Seroma Formation in a Canine Abdominoplasty Model," (Plast. Reconstr. Surg. 2008; Vol. 122, Issue 1: 95-102) the results demonstrated that TissuGlu successfully prevented the formation of seroma in a novel large-animal model designed to evaluate seroma formation. While the control side in all seven animals used in the study demonstrated large, clinically significant seromas, the side treated with TissuGlu showed little or no evidence of fluid accumulation. In addition, histologic analysis of tissue samples from the animals showed no signs of inflammation or foreign body reaction associated with the adhesive.

"I am impressed with the experimental data that demonstrate a clear ability of the adhesive to control seroma formation in this animal model," said J. Peter Rubin, M.D., founder and director of the Life After Weight Loss surgical body contouring program at the University of Pittsburgh and the lead author of the paper. "This adhesive shows strong potential for widespread applications in many surgical specialties."

Surgeons have expressed a strong need for a product that adheres tissue flaps to help prevent the fluid accumulation that occurs between tissue layers after surgery. Surgical adhesives available today fall into two categories: "superglue"-type products that are strong but cannot be used inside the body because they break down into toxic byproducts and "fibrin sealant" products that are biocompatible but create a weak bond and are expensive and difficult to prepare during surgery.

"Seromas have been a major problem for post-surgical patients," said Susan E. Downe
